Our Sleeping Bag is a baby and toddler sleeping bag designed for arms-out sleepers (usually from around 3 months of age). The Sleeping Bag has a slim-fit, stretchy design similar to that of a swaddle and is recommended as baby's 'first sleeping bag' after the swaddling phase is over. Please use your child's weight and height to find the most appropriate and safe size for them. A sleeping bag should be well fitted around the neck and the armholes to avoid your baby slipping through. It should also be bell shaped in the bottom to allow for easy leg movement. Please do not size up to the next size until your child meets the weight requirement, for safety reasons.

Very happy with this purchase for my twins. The sleep bags are soft, comfortable, and well made. They keep my babies warm without overheating, and the quality feels excellent. The zipper is easy to use, especially during night changes, which makes life easier with twins. Great fit and lovely design. Highly recommend for parents looking for safe and comfortable sleepwear for babies.
